Temperature gauge

Any one ever bought just the temperature gauge? Where, for how much?
Or does anyone have an spare IC that could be a donor of a temp gauge??
We had the IC out last week but could not find a new crack in the IC
anywhere, or corrosion, etc. around the gauge. (The original jumpers
I did 60,000 miles ago to fix the standard problems are still fine.)
After putting the IC back in the car, the gauge has been intermittent
again (it had totally died a few months ago) but I need to do
something better before winter. The sensor tested good, again-- so I
need to try now with another gauge.
